How to fetch referenced documents properties in a JavaScript client query.

16 replies
Last updated: Dec 4, 2020
when using the javascript client and I fetch a "location" document with referenced "labels" array, the labels array doesn't contain most of the referenced documents properties. How do I get it to include them?

Is your query using the dereferencing operator (
->
)?

Would you expect this to work?

*[_type == "location"]{
          _id,
          name,
          description,
          image,
          location,
          characters,
          labels->
      }

Hi Richard, could you try something like this?
*[_type == "location"]{
          _id,
          name,
          description,
          image,
          location,
          characters,
          "labels": labels[]->{
            ...
          }
      }

perfect! that works thanks!
Dec 4, 2020, 12:24 PM
is that approach documented anywhere? I don't recall seeing that anywhere
Dec 4, 2020, 12:24 PM
You could probably also just use 
labels[]->
alone - the issue was there: it's an array so it needs 
[]
🙂 You can find some examples over here: https://www.sanity.io/docs/query-cheat-sheet#object-projections-4ff061cc51e4
